It depends on what Global Warming means to you. If Global Warming is a dramatic and very threatening event that, very soon, will [gasp] melt the polar ice caps, then no, science is very clear that this is not true, due to documentation of rising heat over time. If Global Warming is a gradual and slow event that, eventually, in thousands or even millions of years, might melt an icecube a minute faster, then I believe that, indeed, it is true, because scientists have documented a gradual increase of heat over time. Either way, it is irrelevant to the present time. Let our children fix it.
